Answer:
33 centimeters
Step-by-step explanation:
Because the hypotenuse is the longest side of the triangle, the hypotenuse in the question is 65. The way to solve the question would be to plug the numbers into the Pythagorean theorem.
56^2 + b^2 = 65^2
b^2 = 1089
b = 33
Answer:
5494
Step-by-step explanation:
Assuming all members of each set registered, the total number is ...
2(2697) +3(29) +4(2) +5(1) = 5494
__
Since you're concerned with order of operations, perhaps you want to see the working out.
= 5394 + 87 +8 +5 . . . . perform all the multiplications
= 5481 +8 +5 . . . . . . . . . perform addition left to right
= 5489 +5
= 5494
Answer:
124%
Step-by-step explanation:
We can find the percent of the goal that she achieved while dividing the amount of time she exercised by the time she set as a goal. So, we have to figure out the value of 93/75. This is equivalent to 1.24. We can find 1.24 as a percentage by moving the decimal point over 2 (124) and then adding a percentage sign (124%). And that's the answer.
Hopefully that's helpful and all makes sense! :)
